T0 LZZ who/11, t may concer/b.-

Be it known that l, FRANK CnEAssEr, a subject of the King ol Great Britain, and a resident ol the city of Nottingham, in the county ol the said city, England, have invented new and useful Improvements in Lace, ol' which the following is a specification.

This invention has reference to improvements in bobbin lining Valenciennes and similar laces made from the warp on twist lace machines of the Levers type, the object of the invention being the production ol a lace having a net which is thinnel` than the net produced by the ordinary method, whereby the bobbin lining patterning ell'ects are more prominentlyT shown in contrast with the surrounding net.

Tn the accompanying drawings z-Figure 1 is a drawing of apiece olilace made according to the general method. Fig. 2 is a drawing of a piece of lace made according to this invention. Fig. 3 is a drawing, to an enlarged scale, illustrating the arrangements of the threads in a piece of lace made according to this invention. Fig. 4 is a transverse section of an ordinary lace machine which is referred to in the explanation of the method of making lace according to this invention. Fig. is a part front elevation of an ordinary lace machine, and Fig. 6 is a diagrz'nnmatic section of part of an ordinary lace machine.

In a machine used for making lace according to this invention the warp threads A are all drawn 'from a beam b and pass through a fixed sley c and through thread guide bars d to the work roller c. are drawn from bobbins q which are litted to revolve in carriages or shuttles 7L, and these latter are moved to and liro between the back combs or guides and the front combs i by catch bars 7c, while the crossings or twists el the bobbin and warp threads are taken up by point bars l. There are two warp threads to each bobbin thread, and the guide bars (l which carry the warp threads are connected to and actuated by the jacquard m.

In the manufacture ot' bobbin lining laces made from the warp a certain number ol' warp threads are required to produce the bobbin lining ell'ect, and previous to this invention all the warp threads used in a bobbin lining ellect have been incorporated in thenet made between the bobbin lining ell'ects, with a result that the net has been thick and heavy as illustrated in Fig. l. ln

The bobbin threads j" i this drawing the shaded spots and the shaded l portion at vthe lower edge ol' the lace represent bobbin lining ellects and between any two spots in the same row, and between opposite points in the lining at the edge, the warp threads used lor the bobbin lining eflect are incorporated in the net, and unnecessary warp threads are used in other portions ol the net in order to produce a net ol' equal thickness throughout. The spot is shown as an illustration only, and in some patterns one part or other el! the design would or might extend from one edge el the lace to the other edge.

According to this invention the bobbin lining ell'ects in the lace are made l'rom the same number ol bobbin and warp threads as are required in previous met] uds, but alter the bobbin lining ell'ect is linished certain warp and bobbin threads twist together to form the net, while the remaining warp and bobbin threads twist together to/l'orm clips which are afterwards cut away, thus leaving the lace with bobbin lining ellects of the same density as ordinarily produced and having a net much thinner than heretofore.

ln the drawing Fig. 2 the bobbin lining ell lects are shown by the shaded portions Vand the clips by the thick horizontal lines at the lelt side of the drawing, the right hand portion olt the drawing showing the linished lace.

ln the diagram Fig. 3 the bobbin lining ell'ects n and ln/ are produced by twisting together the warp threads a to al with the bobbin threads f to f in the combinations shown, and at the completion ol thel lining ell'eets the clips o are l'orined by twisting thel warp threads in the pairs, n? a, a al, and al a, respectively with the bobbin threads f, f3 and f5, while the net p between the bobbin lining el'l'ects a and n is produced by twisting together in the combinations shown, the warp and bobbin threads not used for the clips. To obtain this result the warp threads are, in one arrangement, threaded through the guide bars d, as shown in Fig. 6 and lor the making ol the bobbin lining ell'ects all the bobbin and warp threads embraced by the breadth ol the el"- i fect, work and twist together in the usual manner.

During the making ol the net, the net making bobbin threads at certain motions ol the machine pass to and l'ro between the clip making warp threads without twisting with them, while at other motions of the machine,

the clip making bobbin threads pass to and fro between the net making warp threads without twisting with them, but each set of bobbin threads twist with their own warp threads when passing to and fro between the other warp threads.

The number of clips in a breadth of lace is varied according to the attern, and the threads are divided theoretically into net and clip threads as may be required. The clips maybe formed on the back 0r front of the lace, or at the back and front according to the requirements of the lace.

What I claim as my invention and desire to secure by Letters Patent in the United States is l. A lace fabric made from the warp having therein bobbin lining patterning effects made from all the warp and bobbin threads embraced by the width of the ning effects, and having a net between such iining eiects made from a less number of warp and bobbin threads than is used Jfor the i'ining effects substantially as herein described.

2. A lace fabric made from the warp having therein bobbin ining patterning effects made Jfrom all the Warp and bobbin threads embraced by the width of the ining effects, and in which, between the ining effects some of the warp and bobbin threads used for the ining effects twist together to Jform the net, while the other warp and bobbin threads twist together to form clips which are afterwards cut away from the lace substantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. l

FRANK CREASSEY.
